Description

本発明は、複数の流体を熱交換させる熱交換器に関するものである。 The present invention relates to a heat exchanger that exchanges heat between a plurality of fluids.

従来より、２つの流体同士で熱交換を可能にした熱交換器が知られている。例えば、特許文献１、２に記載の熱交換器では、トランスミッションオイルと冷却水とを熱交換器に導入し熱交換することが記載されている。しかしながら、電動車に搭載される駆動用バッテリは、低温環境下での加温と高温環境下や発熱時の冷却が必要であるため、バッテリの加温と冷却を1つの冷媒で行う場合には、当該冷媒を加温するための熱交換器と冷却するための熱交換器が必要となる。そこで、特許文献３では、３つの流体を導入して熱交換を可能にした熱交換器が提案されている。 Conventionally, heat exchangers that enable heat exchange between two fluids have been known. For example, in the heat exchangers described in Patent Documents 1 and 2, it is described that transmission oil and cooling water are introduced into the heat exchanger to exchange heat. However, the drive battery mounted on the electric vehicle needs to be heated in a low temperature environment and cooled in a high temperature environment or when it generates heat. Therefore, when heating and cooling the battery with one refrigerant, it is necessary. , A heat exchanger for heating the refrigerant and a heat exchanger for cooling are required. Therefore, Patent Document 3 proposes a heat exchanger in which three fluids are introduced to enable heat exchange.

本実施形態の熱交換器５では、図２及び図４に示すように、第３流路層３５、第１流路層１５、及び第２流路層２５が、上方から下方にこの順に繰り返し設けられる。言い換えると、複数の第１流路層１５の流路層が、複数の第２流路層２５の流路層と複数の第３流路層３５の流路層との間に配置される。この構成によれば、第１流路層１５が第２流路層２５に接するとともに、第１流路層１５が第３流路層３５に接するので、第１流路層１５のバッテリ流体Ｗ１の加温及び冷却を効率的に行うことができる。 In the heat exchanger 5 of the present embodiment, as shown in FIGS. 2 and 4, the third flow path layer 35, the first flow path layer 15, and the second flow path layer 25 are repeated in this order from top to bottom. Provided. In other words, the flow path layers of the plurality of first flow path layers 15 are arranged between the flow path layers of the plurality of second flow path layers 25 and the flow path layers of the plurality of third flow path layers 35. According to this configuration, since the first flow path layer 15 is in contact with the second flow path layer 25 and the first flow path layer 15 is in contact with the third flow path layer 35, the battery fluid W1 of the first flow path layer 15 is in contact with the third flow path layer 35. Can be efficiently heated and cooled.

また、熱交換器５の層構成はこれ限らず、例えば、図５の変形例に示すように、第３流路層３５、第１流路層１５、第２流路層２５、第１流路層１５、が上方から下方にこの順に繰り返し設けられてもよい。言い換えると、複数の第２流路層２５の流路層及び複数の第３流路層３５の流路層は、互いに隣接せず、且つ、複数の第１流路層１５の流路層と隣接する。この構成によれば、複数の第２流路層２５の流路層及び複数の第３流路層３５の流路層は、互いに隣接しないので、加温用流体Ｗ３が空調用流体Ｗ２によって冷却されたり、空調用流体Ｗ２が加温用流体Ｗ３によって加温されたりするのを抑制できる。 Further, the layer structure of the heat exchanger 5 is not limited to this, and for example, as shown in the modified example of FIG. 5, the third flow path layer 35, the first flow path layer 15, the second flow path layer 25, and the first flow flow are used. The road layer 15 may be repeatedly provided in this order from the upper side to the lower side. In other words, the flow path layers of the plurality of second flow path layers 25 and the flow path layers of the plurality of third flow path layers 35 are not adjacent to each other and are the flow path layers of the plurality of first flow path layers 15. Adjacent. According to this configuration, since the flow path layers of the plurality of second flow path layers 25 and the flow path layers of the plurality of third flow path layers 35 are not adjacent to each other, the heating fluid W3 is cooled by the air conditioning fluid W2. It is possible to prevent the air conditioning fluid W2 from being heated by the heating fluid W3.

It is formed between two plates 53 which are overlapped with each other through a gap between the two plates 53. Since each flow path layer is formed between two plates 53 that are overlapped with each other through a predetermined gap, the heat exchange efficiency can be adjusted by adjusting the gap. The number of plates between adjacent flow paths may be one, two, or three or more.
